INTRODUCTION

AQUA STEAM 6-12Kw BKW and AQUA STEAM 18-24Kw BKW

The AQUA-STEAM GENERATOR series have many unique features that make them superior to other steam generators in the market place. They have been designed to give maximum performance, easy installation, easy operation and low maintenance costs. The most important point of all for the user is that they produce the freshest steam possible! Steam quality can deteriorate due to poor water quality and this can result in unpleasant odours’. The AQUA STEAM GENERATORS overcome this problem with a unique patented automatic solids reduction system that ensures that solids in the water are kept to a minimum and water freshness to optimum purity with our automatic flushing facility which drains the stale water.

The commercial control is electronic with digital display of required temp (set point) actual temperature and a 7 day timer. The cubicle control and temperature sensor are stainless steel and pre-wired for easy installation.

The 22mm steam outlet is polished metal and has a venturi essence diffuser.

Various sizes of steam generators are available to suit the particular size and materials used in the construction of the steam enclosure. Each model of steam generator has three power settings. (See table below). This allows our generators to cover various sizes of steam rooms.

MODEL POWER SETTINGS1 COMMERCIAL BJ 6-12KW 6,9,12KW2 COMMERCIAL BJ 18-24KW 18-21-24KW

Please note that whatever steam generator from which ever manufacturer you choose the water quality is of paramount importance. Poor water quality will inevitably mean more frequent servicing. The BJ series of auto flush generators with the patented solid reduction system greatly reduces servicing down time compared to non patented systems.

INSTALLATION & FITTING

COMMERCIAL STEAM GENERATORS

BJ6-12AkW & BJ18-24AkWBJ6-12BkW & BJ18-24BkW

NOTE: - Before the installation of this machine, please make sure you read these instructions thoroughly Failure to install this machine in accordance with the manufacturers recommendations might invalidate the warranty. Should you have any queries or require technical advice, contact your distributor who will put you in contact with our technical department. The electricity supply must only be connected to the unit by a suitably qualified person in accordance with local regulations.

STAGE ONE: - Sighting and Fixing the Generator. A minimum space of 1100mm for width and 1000mm for height should be allowed, with proper access for servicing the generator and the descaling cap. (See detail 5 Fig 2) Determine a clean dry place where the steam generator is to be fixed (emphasis on the surface being secure and the unit being properly supported). The unit is not suitable for installation in a damp or wet area. Screw the generator to the wall, through screw holes (see dimensions on Fig 2) Make sure the generator is both vertical and horizontally level. Allow 300mm minimum height from the floor, to leave space for drainage of solids into a container. A minimum space of 400mm from the cleaning access cap(s) (see Fig 2) from the unit should be permitted for cleaning with the brush provided. Once the generator has been fixed, the anchor screw must be fitted to prevent the generator from being accidentally moved. Should the generator be boxed in, an access door or panel must be fitted to allow for easy access and maintenance of the generator unit without damaging the decoration, you should also make an allowance for ventilation minimum 100mm x 100mm.

STAGE TWO: - Water SupplyGenerally the water supplied from any regional water authority is of sufficient quality to use with the Aqua-Steam generator. Greater care is perhaps required if water is from a well or bore hole particularly if the iron content is high. Such water should be avoided. If requested the water authority will advise on the scale content (hardness) of the water supplied. In situation where the water hardness is greater than 100 ppm it is recommended that a monospheric water softener be incorporated to supply the generator especially if the unit is to be in frequent use. Alternately inspect the unit for scale after every 100 hours of use and de-scale as necessary – see descaling instructions. We recommend that a washing machine hose is fitted to the 3/4” BSP male thread of the solenoid valve (detail 1 Fig 2) and connect the other end of the hose to a servicing valve so the water supply can be isolated. The hose is also useful for flushing the tank and pipe work during maintenance etc. A minimum water pressure of 0.5 bar and maximum 10.0 bar must be provided for the correct operation of this machine.

STAGE THREE: - Fitting Steam OutletThe maximum pipe run must not exceed 20 Mtrs length and must be of 22mm diameter. The pipe work should be installed in such a way as not to create air locks. Long radius bends should be used or pulled bends to reduce restriction of steam. The pipe must be adequately lagged to avoid heat loss and condensation of steam. The BJ 18-24 generator has two independent steam outlets; each must be fitted as above but totally independent from each other. When pipe is increased over 10 Metres a higher power setting may be necessary. It is bad practice and a frequent source of failure to inject essence into the steam pipe(s). Even in very large diameter pipes the fillers and plasticisers used in the essence quickly block the pipe and also back up into the generator.

STAGE FOUR: - Auto-flushingConnection to the discharge solenoid valve is 1/2” BSP thread and the drain line must be a minimum of 15mm diameter heat resistant pipe and must have a minimum fall of 1.5 degrees to an open drain, washing machine trap or similar. Keep the pipe run short with as few bends as possible as it will otherwise fill with scale.

STAGE Five: - In the CubicleFit either the BKW temperature sensor or the AKW cubicle control. The BKW sensor should be fitted approximately 2Mtrs above the floor away from the steam outlet in a safe position. The AKW cubicle control if fitted should be approx l.8mtrs above the floor away from the steam outlet. We recommend that shower type silicone sealant be used around the stainless steel trim and box assembly of the cubicle control to fix the unit to the wall. Connect plug on lower right hand of attendant control box.

Page 6

STAGE SIX: - Fitting 12v Electronic Attendant Control9This control must be fitted in an easily accessible dry place for the operation of the attendant. When the control is fitted to the wall then connect plugs coming from the control to the sockets on relay board inside left hand of generator box. NOTE extension leads are available if required. Also make sure exposed connectors are protected with water proof tape.

STAGE SEVEN: - Computer Management Link You only need to connect a 2 wire lead with a gland inside lower left hand of attendant control. These wires must go to a volt free contact at the computer, when contact is made (closed) generator will start, when contact is (open) generator will stop. NOTE: control switch must be on timer mode and the timer switch “OFF” to synchronies with computer. This function is available as standard on the AKW control but only by special order on the BKW control.

STAGE EIGHT: - Power (Kilowatt) selection for BJ6-12 & BJ18-24For BJ6-12 the fixed minimum power is 6kW. To increase to 9kW insert link pin (detail 10 Fig 2) and to increase to 12kW also insert link pin (detail 10A Fig 2). For model BJ18-24 the minimum fixed power is 18kW. To increase to 21KW fit link pin (detail 10 Fig 2), to increase to 24KW fit link pin (detail 10A Fig 2). Link pins are to prevent power being accidentally increased. Cable should be adequately sized to suit the power requirement. Note: setting the generator on a higher power than necessary may result in the cubicle remaining for relatively long periods at a temperature above the set point with no steam. Only use the minimum power necessary.

STAGE NINE: - Connection to Power supplyThe BJ6-12 is set for three phase but can be modified to single phase use by inserting a link connector supplied (detail 6A Fig 2) into connector (detail 6 Fig 2). By tightening the three screws the machine will be converted into single phase operation. The BJ18-24 is three phase only. When connecting cables to power supply it is advised that conduit be used and connected via hole (detail 6B Fig 2) with the appropriate fitting. 220-240v AC. for single phase, 415v AC. for three phases 50-60Hz. The steam generator must be earthed and connected to a residual current circuit breaker with a minimum of 30 mille Amps sensitivity and connected through an isolating switch with minimum of 3mm breakage across all poles. The correct fuse must be fitted for the power selected. For technical specification see page 2. NOTE all mains connections must be thoroughly tightened and it is good practice to re-tighten all power connections within the generator since copper conductors may have “eased back’’ in their terminals in transit.

STAGE TEN: - Essence Doser unit (optional extra)This machine is provided with a 220-240v AC. 5 amp fused terminal connector (detail 18) and PG7 cable gland (detail 18A) for essence doser connection, this will energies when steam is produced. For further details contact your supplier.

STAGE ELEVEN: - Commissioning GeneratorRe-check that the unit is installed in accordance with the instructions before switching mains power on. Please check that the water supply is “ON” with sufficient pressure 0.5 bar, (3 meters head). Switch power “ON” and you will see a green light on the generator and an intermittent one on the AKW attendant control or a further steady green light on the BKW control (that means the generator is ready to start) now follow the operating instructions. Once the generator is operating switch off and drain the generator to clean plumbing flux etc from inside. Do this twice and finally check for leaks. If you need any further information please do not hesitate to contact our technical department.

Please leave instructions with client and demonstrate how to de-scale the unit.

OPERATING INSTRUCTIONS - AKW CONTROL

ATTENDANT CONTROL (All connections to the control unit are 12V A.c. or D.C.)

Unlock the clear lid with a screw driver. Then press the side next to the lock and the clear lid will open, press the control “ON” the system is then in standby mode and you should see a green intermittent light, this means the power is on and you can start to operate the generator in one of three ways.

CUBICLE CONTROL STANDBY 32 MINUTES AUTO STOP MODE

To operate in this mode, you must first set the switch on the attendant control to “32 minutes auto”. The steam generator will only work when the user inside the cubicle pushes the start button. A red intermittent light will indicate that the generator is “ON” then it will stop automatically after 32 minutes.

ENERGY SAVE AUTO-STOP 32 MINUTES

This mode is normally used by the attendant in periods when the cubicle is not busy so as to save energy. You can switch the cubicle on for 32 minutes by pressing the top left button next to the time remaining indicator and you can stop the system by pressing the lower button.

SEVEN DAY TIMER MODE

With this function you can program the generator to be switched “ON” Twice and “OFF” Twice during each individual day of the week. (Minimum “ON” time is two hours).

COMPUTER LINK MANAGEMENT SYSTEM (optional extra)

This link will allow you to switch the generator “ON” or “OFF” from a computer but the control switch must be positioned in “timer mode” and the timer switch must be “OFF” for the computerised system to take control.

TEMPERATURE ADJUSTMENT

You can adjust the temperature by pressing the arrows up and down next to the thermometer, where an intermittent light tells you the setting of the temperature and a series of steady lights tell you the actual cubicle temperature.

If you switch off the attendant control unit you will over-ride the computer link and any other function for servicing and in an emergency always switch the generator “OFF” at the mains.

Note that the generator is supplied with the temperature pre-set at 35C In order to change this setting first set the temperature required as described above and then turn the control off by using the OFF button on the touch pad. When restarted, the system will then start up using your preferred operating temperature.

OPERATING INSTRUCTIONS - BKW CONTROL

ATTENDANT CONTROL (All connections to the control unit are 12V A.c. or D.C.)

Unlock and open the clear lid as described in the AKW instructions above.

7 DAY TIMER

With this function you can program the generator to be switched “ON” Twice and “OFF” Twice during each individual day of the week. (Minimum “ON” time is two hours).

OPERATING INSTRUCTIONS BJ6-12KW & BJ18-24KW

Page 10

COMPUTER LINK MANAGEMENT SYSTEM

This link will allow you to switch the generator on or off from your computer but the timer switch must be in the off position. This function is only available by special order.

TEMPERATURE ADJUST

The digital thermostat displays the temperature at the sensor in the steam room, to display the set point press and hold the thermometer button. Should the set point need adjustment continue to hold the thermometer button and at the same time use the up or down arrow to select the required temperature. Release all buttons.

START UP DISCHARGE

The BKW control is designed so that it may also be used in conjunction with an Automatic Descaler. When descaling is completed and the generator restarts a brief heating cycle (10 seconds approx) is initiated followed by a 4 minute discharge (approx) and delay before the generator refills and starts to heat up. This discharge can be over-ridden by using the on/off switch on the bottom right of the control, turning it on, off and on again.

REMOVAL OF WATER DEPOSITS

If a water softener is fitted always ensure that it is not allowed to function without salt and that it only back washes at a time when the steam generator is not in use. If the water softener is working correctly removal of water deposits will not normally be necessary. When the steam generator has cooled down drain the generator by holding the “DUMP SWITCH” on the control isolate the machine at the main power switch. Then place a container of minimum of 5ltr capacity under the lower access cap. Remove the access cap by hand, turning anti-clockwise, releasing the water residue. With the brush provided clean inside the bottom of the tank to remove any flakes of scale. Replace access cap hand tight only; please be careful not to cross the threads. Check for leaks. Switch on mains power and your regular maintenance is now complete.

SCALEScale is the primary concern in heavily used generators and an auto de-scale unit is available for use in conjunction with th BKW control and commercial generators. The auto de-scale adds descaler to the generator when it is switched OFF at night. It is a feature of the BKW control that at start up from the time clock the generator will be instructed to heat for a few seconds and then dump the entire contents of the tank over a 4 minute period, to remove any descaler that may have been added. This ensures that the unit contains fresh water before steaming begins. If an auto de-scale unit is not fitted or during testing, the 4 minute delay period can be overridden by switching the control ON/OFF switch from ON to OFF and back to ON again.

Page 11

DESCALING

The steam generator manufacturer cannot accept responsibility for the quality of the water fed to the unit. Water quality varies from area to area and with the time of the year. Any warranty will be invalid if the generator is not kept free of water solids and scale. This means ensuring only adequate clean water is supplied to the generator i.e. less than 100 parts per million of impurities. (See note 2) The steam generator must be checked regularly and if necessary de-scaled. If there is any doubt it is better to de-scale the unit and typically this will need to be done every 100 hours of operation. Descaling is a relatively simple task but is important in order to keep the steam generator in good condition and prolong the life of the unit. The auto flushing Steam Generator will greatly reduce the build up of scale and ensures optimum freshness of steam. The frequency at which descaling is necessary is also greatly reduced compared to other manufacturers products which do not incorporate the patented auto flush system.

If a water softener is fitted make sure that this does not recycle when the generator is in use. Descaling may need to be carried out every 100 hours of use in very hard water areas. For safety reasons only use citric acid descaler from your supplier.

During descaling the machine must be isolated from the electricity supply at all times, never use this appliance during descaling and make sure that all the de-scalent is removed before the steam facility is used again.

1. For the purpose of descaling steam generators, use non poisonous and non corrosive de-scalent (citric acid.)

2. Allow the generator to cool before remove the descaling cap by turning anti-clockwise. Mix the de-scalent to manufacturers instructions and with a funnel pour the solution into the generator. Fit the filler cap back on the unit.

3. Leave the de-scalent in the generator for as long as instructed. (Typically 5-24 hours)

4. Flush the generator thoroughly to ensure that all traces of de-scalent are removed. Note that with the tank empty it is useful to unscrew the 40mm access cap (detail 4a Fig 2) and clean out any large pieces of scale that may remain. The auto-flushing steam generator will rarely need descaling unless the water quality is extremely poor. The service engineer will find a push button inside the cover to open the electrical flushing valve manually if necessary.

NOTE: In severe cases some de-scalent may enter the steam pipe and the steam outlet, should this happen the pipe must be flushed with clean water, from time to time this is also useful to prove that the steam pipe is not blocked.

FLUSHINGOptimum steam quality can only be achieved if the generator is filled with the purest possible water. Boiling or extremely hot water could be released when the drain valve (see detail 4) is opened so it is important that due care be taken and preferably that the unit should be allowed to cool slightly before the drain valve is opened.

If a water softener is fitted and working correctly descaler should not be needed however an unmaintained softener will provide no protection against scale. It is advisable to inspect the inside of the tank at least every month. If proper maintenance is not carried out and scaling occurs for any reason warranty of the tank will be void.

WARNING:During descaling the machine must be isolated from the electricity supply at all times. Never try to use the appliance during descaling and make sure that all the descaler is removed before the steam facility is used again.

CAUTION:The user must be made aware that due care must be taken particularly with children and the infirm when using this equipment. If in doubt seek medical advice. Leave the instructions with the client and ensure that they understand how to use the facility.

NOTE: To prolong the life of the generator and reduce the inconvenience of manual descaling an automatic descaling unit is available from your distributor

INDICATORS

AKW INDICATORS CONTROL UNIT The two alternating green indicators at the bottom of the thermometer show that low voltage power is available at the control unit. When the control is turned on the steady indicators on the thermometer show the temperature. The flashing indicator on the thermometer shows the current set point (or required temperature). The clock indicators each represent 4 minutes giving 32 minutes if all are on.

BKW INDICATORS CONTROL UNIT

When the control is active the digital display shows the temperature. To check the set point press ******* If adjustment is required then press the up and down arrows as necessary. Once set the display will resort to displaying the actual temperature after approximately 5 sec.

STEAM GENERATOR INDICATORS

There are four indicators on the Steam Generator see Fig 2:-

Item 14 GREEN Shows mains supply is connected to the generator and switched on.

Item 12 RED (upper) Comes on whenever the control is on and the generator requires more water.

Item 13 RED (lower) Comes on whenever the heaters need to be on to make steam.

Item 15 YELLOW Comes on whenever the supply is on and will change to green only when the control temperature is above the set point.

Item 15 GREEN Cubicle has reached set temperature

Item 15 RED Error state impurities in water or water has reached the high probe
